Katharine Mach is an Associate Professor at the University of Miami Rosenstiel School of Marine and Atmospheric Science and a faculty scholar at the UM Abess Center, focused on environmental science and policy. Her research assesses climate change risks and response options to address increased flooding, extreme heat, wildfire, and other hazards. From 2010 until 2015, she co-directed the scientific activities of Working Group II of the Intergovernmental Panel on Climate Change (IPCC), which culminated in the IPCC’s Fifth Assessment Report and have supported diverse climate policies and actions, including the Paris Agreement.

Robert Lempert is a principal researcher at the RAND Corporation and Director of the Frederick S. Pardee Center for Longer Range Global Policy and the Future Human Condition. His research focuses on risk management and decision-making under conditions of deep uncertainty. He is a convening lead author for Working Group II of the United Nation’s Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report, and the inaugural president of the Society for Decision Making Under Deep Uncertainty.

How can the Intergovernmental Panel for Climate Change’s (IPCC) framework for assessing and communicating uncertainty be related to decision making? One way to attack this question is by confronting the framework with recent decision models proposed mainly by economists working on the theory of decision under uncertainty. The confidence-based decision model developed in the context of this project (see here or here) emerges as best equipped, among major existing approaches, to fully utilise the information provided by the IPCC. Moroever, the connection of IPCC conclusions with decision making via such a model brings out some an apparently novel recommendations for future uncertainty reporting.
